Terror Probe: Unmasking the Killer of An Anti-Taliban Leader

As members of the Northern Alliance make plans to join in a new ruling coalition for post-Taliban Afghanistan, a fog of mystery has remained over the murder of their onetime leader. But as first reported on TIME.com French police have learned the identity of one of the two assassins of Ahmed Shah Massoud, the former commander of the Northern Alliance, who was slain by two suicide bombers posing as journalists on Sept. 9. The alleged killer is Abedessatar Dahman, a Tunisian who immigrated to Belgium and became part of a radical Islamic group with links to al-Qaeda.
